1. Painted on a wall are 4 red triangles, 2 blue triangles, 6 green triangles and 8 yellow triangles. What percentage of the triangles are blue or red?
Jawaban:
red : 20%
blue : 10%
Penjelasan dengan langkah-langkah:
4+2+6+8=20
red : 4/20=2/10=20%
blue : 2/20=1/10=10%
semoga membantu.
Penjelasan dengan langkah-langkah:
4 merah
2 biru
6 hijau
8 kuning
berjumlah = 20 segitiga
segitiga biru dan merah = 4+2 = 6
20 = 100%
1 = (100/20)%
1 = 5%
presentase segitiga biru dan merah :
= (5×6)%
= 30%

9. Find the unknown marked angles in each of the right-angled triangles.tolong bantu dong
Jawab:
a. 180° - (90° + 57°)
180° - 147°
= 33°
b. ∠ABC = 180° - (90° + 28°)
= 180° - 118°
= 62°
∠ADC = 180° - {90° - (90° - 28°)}
= 180° - (90° + 62°)
= 180° - 152°
= 28°
c. ∠GEF = 180 - (90 + 26)
= 180 - 116
= 64
∠DEG = 90 - 64
= 26

Problem9
Let
[tex] \xi = \{x \colon x \text{ is an integer and } -3 \le x \le 3 \} \\ [/tex]
[tex] A = \{x \colon 2x + 1 < 5 \} \\ [/tex]
[tex] B = \left \{ x \colon \frac{x}{3} \text{ is an integer} \right \} \\ [/tex]
(a) Express the set [tex] A [/tex] by listing its elements.
(b) Is [tex] -4 [/tex] an element of [tex] A [/tex]? Explainyour answer.
(c)Write down the common elements of [tex] A [/tex] and [tex] B [/tex].
Solution
For part (a), the set of [tex] A [/tex] can be written as
[tex] A = \{-5, -3, -1, 1, 3 \} [/tex]
For part (b), [tex] -4 [/tex] is not an element of a set of [tex] A [/tex] because [tex] A [/tex] is a set of odd numbers with [tex] x \in [-3, 1], x \in \mathbb{Z} [/tex].
For part (c), both sets can be written as
[tex] A = \{-5, -3, -1, 1, 3\} [/tex]
[tex] B = \{-1, 0, 1\} [/tex]
